Chris Ruger is used to answering questions about guns. An expert gunsmith and proprietor of what he calls Ulster County’s only independent gun shop “That isn’t a kitchen table operation,” Ruger knows firearms from muzzle to butt-plate. As a federally licensed gun dealer he knows intricacies of firearms sales across the country’s patchwork of laws and regulations. Which may be why he appears frustrated on a snowy Monday morning as he attempts to field a steady stream of questions from customers about New York State’s sweeping new gun legislation.
